Figure 15: Configuring asymmetric bridges for GPON
We will use VLAN 300 for the VoIP bridge, and connect out to the
Metaswitch softswitch server using SIP.
Figure 16: Configuring TLS bridge for GPON
The behavior of the TLS bridge is better suited for upstream initiated calls
because the TLS VoIP bridge (VLAN 300 in our example) will be flooded
with a request for the MAC address of the VoIP access device if the MAC
address is timed out from the MXK’s forwarding table. Asymmetric bridges
do not forward unknown unicast which are received on the uplink, so an
asymmetric bridge is not a suitable option for the voice application.
